This document discusses social espionage, which involves drawing competitive intelligence from rivals' social media presence. Social espionage combines traditional competitive intelligence gathering with analysis of information on social media to gain strategic advantages. It outlines how firms can now access customer relationships through social media and describes tactical, operational, and strategic activities that constitute social espionage, such as intercepting messages, encouraging customer switching, and identifying weaknesses. Benefits include gaining insights at tactical, operational, and strategic levels, but it also carries risks. The document advocates a strategic grid approach and defines social espionage as a combination of competitive intelligence, social media monitoring, and a "Machiavellian" mindset.
